[Theoretical principles of "contactless" tonometry].

The authors present a short recapitulation of the capabilities of modern applanation tonometry and point out its limitations. They discuss the two methods, "non-contact" and "contactless" tonometry. The latter, which has been recently developed in Hungary, differs from Grolman's in that it employs an electonic system to measure the applanation, which is induced by an air jet. With this method the accuracy of the recording enables events lasting only fractions of a second to be studied in a variety of ways while measurements are being made.

[Replacement of the tympanic membrane by corneal transplantation (keratomyringoplasty)].

The authors present a new method of the substitution of the ear-drum with cornea transplantation, applied with success in 28 cases. They have established that the various tissues (skin, veins fascia, etc.) applied up to now for myringoplastic are not so suitable as the cornea, because the latter is similar to the ear-drum, according to its histological construction and physical properties. The execution of the operation, the technique of the removal of the cornea from a corpse, as well as the preparation of the auditory meatus and the inserting of the cornea are discussed in detail. The removal of the cornea can be carried out in its whole or lamellated. In contrast to ceratoplastic, the cornea need not remain transparent in ceratomyringoplastic, because, in the latter case, only its tectorial and sound-conduction effect is needed.

[The different forms of hypermetropia and the necessity of their precise correction (author's transl)].

The author presents a detailed analysis of hypermetropia. He defines its three pathogenetically important forms:--facultative, relative and absolute, starting from the principles of Donders and based upon the dioptrics of Gullstrand. The author then deals with the pathological processes caused by hypermetropia, especially with the formation of strabismus. Finally he discusses the effects of the three forms of hypermetropia and of the associated other deficiencies of refraction.
